In this episode of Philip Marlowe, the detective is drawn into a tangled case involving a priceless jeweled seahorse brooch, a bitter family feud, and a few too many “friends” with hidden agendas. After being hired to oversee the sale of the brooch, Marlowe arrives to find his client dead and the treasure missing. The trail leads through a red-haired stepdaughter with something to gain, a seafaring brother-and-sister pair with secrets of their own, and a long-suffering companion whose loyalty masks something darker. As deception piles on deception, Marlowe uncovers how greed, resentment, and desperation can twist even familiar relationships into something deadly.
